Cutting equipment and knife-damaging-resistant device thereof

Abstract

The invention discloses cutting equipment and a knife-damaging-resistant device thereof. The knife-damaging-resistant device comprises an electricity conducting part, a power supply, a current sensing device and a hint device. The electricity conducting part is arranged below materials to be cut. After a knife cuts off the materials, a part exposed from the inner portion of the materials is in contact with the electricity conducting part. When the materials are not cut by the knife, the knife and the electricity conducting part are isolated by the materials. One electrode of the power supply is connected with the knife in a conducting mode. The other electrode of the power supply is connected with the electricity conducting part in a conducting mode. The current sensing device is used for sensing whether currents exist in a closed loop formed by the power supply, the electricity conducting part and the knife. The hint device is in communication connection with the current sensing device. When the current sensing device does not sense currents, the hint device gives out hint information. According to the cutting equipment and the knife-damaging-resistant device thereof, knife damaging problems can be effectively avoided, and compared with the fact that in the prior art, a photoelectricity sensing device is used as a knife-damaging-resistant device, working efficiency can be effectively improved.

Description

technical field [0001] The invention relates to the technical field of cutting equipment, in particular to a cutting equipment and an anti-collapse knife device thereof. Background technique [0002] In the process of radial tire fiber cord processing, it is necessary to cut the wide fiber cord to the actual required width. However, in actual production, the fiber cord will inevitably wrinkle on the cutting platform, and the thickness of the fold position is large, which will cause the cutter The fiber cord cannot be cut continuously, which leads to the problem that the blade of the cutting knife will collapse when cutting at high speed. [0003] In the prior art, in order to avoid knife collapse, a photoelectric sensing device is used to sense whether the fiber cord is wrinkled. When the fiber cord is wrinkled, the photoelectric sensing device sends a sensing signal to stop the cutting equipment. Manually process the fiber cord before continuing to cut. [0004] However, ...

AI Technical Summary

Problems solved by technology

[0004] However, when the fiber cord is not cut due to wrinkles, for example, when the fiber curtain layout part material is unqualified material, there may be a problem of continuous cutting by the cutter. At this time, the photoelectric sensing signal does not sense the fiber There is a problem of wrinkles in the curtain, and the equipment continues to run, which may easily lead to the problem of knife collapse

[0005] In addition, when the thickness of the cut fiber cord
